It is the CAI 207g trail. Going down from Viale Europa on asphalt and then on a dirt road along Via Romania, a beautiful trail begins in the woods that, with the crossing of two fords of the Cremera stream, allows us to reach the splendid Valle del Sorbo. The trail is easy, slightly downhill coming from Via Romania, and then completely flat along the banks of the stream in a beautiful gorge with a couple of waterfalls. The trail is completely rideable, without rocks or steps. The two fords, if you are on foot, are crossed by walking on stable stones with the help of trekking poles; with a lot of attention you can pass and not get your feet wet. The flow of water should never be excessive as the sources of the Cremera are a couple of km before, near the sanctuary of the Madonna del Sorbo. The three of us, with bikes, did not get wet. To be safe, bring two plastic bags to cover your shoes. The trail is not suitable for families with children in strollers.

The Valle del Sorbo is an enchanting valley in the Parco di Veio, located just 30 kilometers from the capital Rome. It is a “Site of Community Interest” due to the presence of the characteristic tuff valleys of the Roman countryside. The valley, crossed by the Fosso della Mola (later named Valchetta), extends between Formello and Campagnano di Roma and is populated by livestock kept in the wild. It is one of the most visited places in the park. The valley is also home to the Santuario della Madonna del Sorbo, an important stop on Lazio's Via Francigena.

The Tagliate, or dark quarries, are very ancient roads carved into the sulphurous rock. The Tagliata Fantibassi is about 190 meters long, its walls are about 10-14 meters high, the road is 4 meters wide even if it sometimes narrows down to 1 meter. The average slope of the track is approximately 15%.

The Cavoni appear very similar to the gorges and are one of the most important examples of the impressive engineering works of the ancient Falisci civilization. The communication routes of this ancient people were dug by hand in the tuff.

The canyons around Mazzano Romano are primarily found within the Riserva Naturale Valle di Treja, characterized by dramatic tufa formations and a scenic gorge carved by the Treja River. You'll encounter lush forests, picturesque river flows, and unique geological structures. A notable natural highlight is the Monte Gelato Waterfalls, a beautiful series of cascades along the Treja River, often featured in films.
Yes, the Treja Valley is rich in history. You can explore ancient Faliscan engineering works like The Cavoni of Nepi, impressive hand-carved rock paths dating back 3000 years. Another significant historical site is Tagliata Fantibassi, an ancient road carved into sulphurous rock. The area also holds traces of prehistoric settlements and Roman villas.
The Treja Valley offers numerous hiking trails. You can explore the enchanting Valle del Sorbo, which is part of the ancient Via Francigena route, perfect for hiking or cycling. Another suggestive spot is the area around the Wooden Bridge and Cavoni of Nepi, near the path leading to the Picchio waterfall. For more hiking options, check out the hiking guide for Mazzano Romano.
Many areas within the Treja Valley are family-friendly. For example, Valle del Sorbo is considered an enchanting place for all. The Calcata Loop Trail, an easy 3.5-mile (5.6 km) hike, is also a great option for families to explore the scenic valley and historic village views of Calcata.
The Treja Valley is beautiful year-round, but spring and autumn offer the most pleasant weather for hiking and exploring the canyons, with mild temperatures and vibrant foliage. Winter hiking is also possible, but some trails might be muddy or slippery after rain. Summer can be hot, so early mornings or late afternoons are recommended for activities.
The Treja Valley Regional Park generally welcomes dogs, but it's always advisable to keep them on a leash to protect wildlife and ensure the safety of other visitors. Specific trail regulations might vary, so check local signage. Many trails, including those around the Monte Gelato Waterfalls, are popular with dog owners.
Beyond hiking, the area is excellent for cycling. You can find numerous routes for gravel biking, such as those listed in the gravel biking guide for Mazzano Romano, or explore mountain biking trails, detailed in the MTB trails guide. The Treja River also offers opportunities for enjoying the natural environment.
Absolutely. The entire Treja Valley is a testament to unique geological processes, primarily characterized by dramatic tufa pinnacles and formations. Mazzano Romano itself is perched on such a tufa pinnacle, overlooking the gorge. The 'cavoni' and 'tagliate' are ancient roads carved into the volcanic tufa rock, showcasing both natural geology and human ingenuity.
While direct public transport to the Monte Gelato Waterfalls can be limited, you can typically reach Mazzano Romano by bus from Rome (e.g., Saxa Rubra station). From Mazzano Romano, the waterfalls are accessible via local roads or hiking trails. It's recommended to check current bus schedules and consider a short taxi ride or a walk from the town center.
Hiking trails in the Treja Valley range from easy to moderate. Many paths, like the Calcata Loop Trail, are considered easy. Others, such as the CAI Trail 207g: Via Romania to Valle del Sorbo, are intermediate, involving ascents, descents, and river crossings. Always check individual trail descriptions for specific difficulty ratings.
Beyond the well-known Monte Gelato Waterfalls, exploring the various 'cavoni' and 'tagliate' offers a glimpse into ancient history and unique geological formations that are less frequented. The extensive network of trails throughout the Treja Valley allows for discovery of secluded river bends, ancient ruins, and tranquil forest paths away from the main attractions.
